I'm currently on a aluminium Macbook from late 2008, and I'm trying to decide whether or not I should invest in a new Macbook Air. All this talk about a much improved 'haswell air' makes me unsure if i should buy now or wait. My current system performs relatively well. Boot times are somewhat long, but once running the machine performs well enough. I don't really play games, except for Homeworld which I install on my computer perhaps 2 times a year and after a playthrough delete again. Besides that, I mostly use my current mac for web-browsing, music and word-processing. Is it worth waiting for the haswell air, or should I head out and buy myself an Ivy Bridge air?
